A Domain-by-Domain Checklist for the Cloud Practitioner Exam

The Cloud Practitioner paper scores four domains, from Cloud Technology and Services at 34% down to Billing, Pricing and Support at 12%. This is the whole track on one page, sorted into those four: the cheat sheet that anchors each domain, the situations to work through, and the quizzes and cards to drill. Tick your way down, and wherever a line still feels shaky, that is the next half hour of revision.

One Bill, Nine Teams and Nobody to Ask

A software company with nine product teams gets one AWS invoice a month, and nobody can say which team spent what. A finance business partner wants chargeback, a team lead wants warning before they overspend, and the platform lead wants a support response within the hour rather than the next business day. Three different tools, and one organisational change underneath all of them.

The Same Instance at Four Prices

A market research firm runs 180 instances, all of them On-Demand, and finance wants the bill down without anything being switched off. The estate divides into four groups with completely different demand shapes, and the same instance type is available at four different rates depending on what you are prepared to commit to. What each group can honestly commit to decides the rate it gets.

A Question Nobody on the Team Could Answer

An eleven-person company in Adelaide spends an afternoon on a problem nobody can solve, and works out halfway through that the real difficulty is not knowing who to ask. Five more questions arrive over the next month, and each one has a different route: a support case, a page AWS has already written, somebody else's software, or a partner with hands on the work.

Cheat Sheet: Billing, Pricing and Support

A final-review sheet for CLF-C02 Domain 4: the compute purchasing options and when each fits, storage and data transfer charges, the billing and cost management tools, AWS Organizations and cost allocation tags, the Support plans and their response times, and the partner and technical resources.

Flash Card: Integration, Developer and End-User Services

The rest of the catalogue: messaging and events, developer tools, business applications, virtual desktops, frontend hosting and IoT. Each one is recognised by the single job it does.

Flash Card: AI, Machine Learning and Analytics Services

Two catalogues to know by recognition rather than depth: the AI services that each do one task, and the analytics services that move, query and visualise data. Learn them by the job each one does in a sentence.

A Subnet, a Gateway and a Route Nobody Wrote

A charity moves its donation platform into a VPC and nothing works: the web tier is unreachable, the application servers cannot fetch patches, and the nightly backup to S3 has been failing since the move. The obvious fix to the first of those would put a database full of donor records on a public path. Four symptoms, four different pieces of VPC plumbing, and each one is a component with a specific job.

A Table That Fits and One That Does Not

A ride-hailing company runs everything in one PostgreSQL database: bookings, driver location updates arriving forty thousand a second, session tokens, and the analytics queries that lock the whole thing up every morning at nine. Four workloads in one engine is the problem. Splitting them is a lesson in what each database service is actually for.

Six Petabytes and Nobody Knows Which Drawer

A genomics institute has six petabytes spread across five kinds of data: sequencer output being processed right now, a shared analysis workspace, results served to a public portal, twenty years of raw reads kept for regulatory reasons, and a scratch area rebuilt nightly. One storage service is wrong for all five, and the discriminator is how the data is reached rather than how big it is.
